Task-01 (ASR-T1): Focusing on a full pipeline development of the ASR model from scratch with limited training data condition. The organizer will provide two training datasets. The first dataset is around 5o hours of transcribed data. The second dataset is around 400 hours of untranscribed in-domain data. All participants are required to use only this provided data to develop models including acoustic and language models. Any use of another resource for model development is not acceptable.
Task-02 (ASR-T2): Focusing on spontaneous speech in different real scenarios e.g., meeting conversation, lecture speech. For this task, the organization will not provide training data, participants can use all available data sources to develop their models without any limitation.
The quality of the models will be evaluated by the Syllable Error Rate (SyER) metric.
SyER = (S+D+I)/N

Since there are cases that input speech can be interpreted in different ways, the below rules are applied to mitigate such an issue:
Numbers, dates etc. need to be transcribed in words as they are spoken, not in digits
Common acronyms such as nato, fifa, are written as one word, without any special markers between the letters. This applies no matter whether they are spoken as one word or spelled out as a letter sequence. All other letter spelling sequences are written as individual letters with space in between.
For English words, names of people and places in other languages such as youtube, facebook, are written as it, not in Vietnamese pronunciation.
